Apply Pipe and Filter architecture style for the below scenario. Also, describe it using a diagram.

A petrol filling station is to be set up for fully automated operation. Drivers swipe their credit cards through a reader connected to the pump; the card is verified by communication with a credit company computer, and a fuel limit is established. The driver may then take the fuel required. When fuel delivery is complete and the pump hose is returned to its holster, the driver’s credit card account is debited with the cost of the fuel taken. The credit card is returned after debiting. If the card is invalid, the pump returns it before fuel is dispensed.
